Figure 1. Buck regulator to power noise sensitive loads with an LC filter on the output

Different filtering techniques can be used to reduce the noise of a switching regulator. One that works especially well is an LC filter with an inductor in series with the power flow and a capacitor from the filtered voltage to ground. This type of LC filter creates a double pole in the frequency domain. Dependi
